Hi Gary, Yes as you will have seen from my posts they are still around and like most by-pass filters they really work. This can be quickly ascertained by laboratory Fluids Analysis. In the past, say 35 or 40 years ago, their usefulness and reliability may have been questionable but today with supporting data from analytical labs readily available their reliability and the fact that they actually work is unquestionable. Today with an ever dwindling amount of oil available and increasing pollution worldwide their implementation and use on every vehicle should be paramount. Rather than digging our heads in the sand and saying yes we are building better quality oils today than we have ever done in the past which is true everybody should be looking ahead and minimising oil useage and wasteage through the implementation of these devices as well rather than maximising oil consumption which is increasing all the time due to increasing numbers of vehicles on the road.. Failure to do so is nothing short of complicity with the large oil companies who have exploited and wasted the worlds resources for the last 100 years. B.r., David
